I drove it ten ignition cycles yesterday and about 80 miles of mixed highway and city. The numbers were solid. I drove it to work this morning and checked it once again. Still solid. I'm convinced its going to stay that way at this point. We had a pretty radical temp swing overnight and the numbers are still identical to yesterday.

I jus got tuned from gm stage 1 to trifecta e85. I have a k and n intake. I started throwing p0101 codes alot. Ive cleaned the maf. Any fix for this? Ive read the pages and gonna try to make sure maf is not touching metal intake.

p0101 is caused by a change in cai piping diameter, and increased airflow past the maf sensor, causing it to go above the maf fail frequency.
5 seconds in HP tuners to bump this frequency from 10000 up to 13000 will make this issue dissapear forever.
If it were caused by grounding, I dont think increasing the fail freq would fix the problem....but it does. every time.

I found a source that sells a MAF tweeker that is a harness inline. I'm going to look into it. It will allow us to offset the maf freq to scale it back into the proper window. ZZ performance has it listed on their site.
I had a little trouble with an occasional Missfire also. I used a can of lucas fuel treatment in it and adjusted the plug gaps to .030 from .032 and it hasn,t missed since. Crossed fingers.
Is it fast
Thats intresting that you commented on the -16 to -17 stock. I never checked that before I changed. I know if you get a soft P0101 the engine will go into reduced power and hold the wastegate open. You also won't get a CEL unless it sees it twice in a row. Intresting.
